SM-3KV is one-component short-period seismometer. SM-3KV is
used in seismic observation systems of local and regional zones, for
measurement variations and spectral characteristics of microseismic
background, detection of earthquakes and explosions, analyzing
oscillations of buildings, constructions, machines, etc.
